My teacher told me this, but i just want to make sure for my exams on monday, what is the the quadratic formula used to solve x intercepts in an equation when it is in turning point form?

Hello,
this is only a guess but...
If the vertex has the coordinates V(k, h) the the equation of the parabola is:
. Equation in turning point form.
To calculate the intercepts with the x-axis you use that y = 0:
